I am not able to see the graph related to this. I am able to see a standard rule for getting the Infosphere information but the rule as such was not viewable. Do you have an idea behind how this will work?

I would like to get some basic information regarding this infosphere MHUB thing.

I was do R & D on connector graphs and I need to understand, if we are associating the dataset to EME it is anyway going to fetch the metadata for us.
Why do we still require the source specific Connector graph to fetch the metadata explicitly?

Say for example: I am creating mainframes dataset in my Ab Initio graph output and while checking in my code it is made to associate with EME dataset.
Now my EME will already will metadata for this dataset. Why do we require a connector graph here?

You'll want to control when, what and where a EME TR metadata is uploaded into the Metadata>Hub. The connector graphs give you the control.

Imagine you have multiple EME>TR's, dependency analysis has been sporadically applied, things are quite in a plug and go shape? You'll be thankful that you can protect your Metadata>Hub with this intermediary step

If we are using only one EM , do you think we still require it? Associating it with EME would suffice ?

What I was thinking was we are associating only the dataset of our interest with EME. If we want to get the
entire metadata information about the source type we would be requiring Connector graphs.
Associating it with EME will limit the visibility.
